Background info

Thanks to Greg Pfeil for color-theme-solarized, of which these
themes are a different formulation, providing a different set of faces
and a few different choices. You might want to use his version
instead.

Note that, depending on your version of Emacs, the colors in this
theme may not be rendered accurately. See, for example,
this OS X Emacs bug. A
customizable value color-theme-sanityinc-solarized-rgb-is-srgb
controls whether or not RGB color literals used by Emacs are treated
as sRGB; consider adjusting this value if the rendered colors don't
quite match those on the solarized page.
